OBJETIVE: The advance of research in child and adolescent psychiatry in Brazil heavily depends on the existence of instruments for the investigation of psychiatric syndromes adapted to Brazilian Portuguese. METHODS: This article describes a careful process of translation of the Children's Interview for Psychiatric Syndromes for the purpose of use in research in Brazil. The Children's Interview for Psychiatric Syndromes has a version for parents (P-ChIPs) and a version for children (ChIPS). In this article, the sections of P-ChIPS referring to attention-deficit hyperactivity disorder, oppositional-defiant disorder, conduct disorder, mania/hypomania, anorexia nervosa, bulimia nervosa and psychotic disorders were translated to Brazilian Portuguese. The sections of the ChIPS referring to substance use disorders, social anxiety disorder, specific phobias, obsessive-compulsive disorder, generalized anxiety disoder, separation anxiety disorder, post-traumatic disorders and depression/dysthimia were also adapted. Each section was translated by two independent translators and later discussed in a committee composed of experts in the field of Psychiatry and a professional of the field of linguistics. RESULT: A final version containing an interview for the main psychiatric syndromes was defined. CONCLUSION: The translated P-ChIPS is a helpful instrument in children and adolescent clinical evaluation.

OBJETIVO: Revisar sistematicamente a literatura sobre programas psicoterapêuticos para a esquizofrenia com enfoque em CS, cujos métodos envolvam estratégias metacognitivas. MÉTODOS: Foi realizada uma busca na base MedLine, por trabalhos publicados em inglês ou português utilizando a frase "Social cognition" AND "Schizophrenia" [Mesh] AND "Psychotherapy" [Mesh] e os limitadores "Humans", "Clinical Trial", "Meta-Analysis" e "Randomized Controlled Trial". Adicionalmente, foram elaborados critérios de inclusão para selecionar os trabalhos com abordagem metacognitiva. RESULTADOS: Dezessete estudos foram selecionados, abrangendo essencialmente programas de reconhecimento do afeto facial e de emoções, Teoria da Mente (ToM), imitação e tomada de perspectiva em situações sociais. CONCLUSÃO: A maior parte dos estudos mostrou que seus programas são eficazes para melhorar medidas de psicopatologia, CS e funcionamento social. Futuras pesquisas deverão esclarecer sobre segurança, especificidade e durabilidade dessas intervenções.

Objetivo: Avaliar a qualidade de vida e sintomas de ansiedade e depressão em pacientes com diagnóstico de meningioma e glioma de alto grau submetidos à neurocirurgia oncológica. Métodos: Para a coleta de dados, foram aplicados dois instrumentos validados no Brasil: Hospital Anxiety and Depression Scale (HAD) e Item Short-Form Health Survey (SF-36). Resultados: Foram identificadas diferenças estatisticamente significativas quando comparados os dados do SF-36 de ambos os grupos tumorais, no pré e pós-operatório, nos aspectos: capacidade funcional (p = 0,043), aspecto emocional (p = 0,042) e saúde mental (p = 0,042) referente ao grupo meningioma. Quando comparados com respectivos grupos controle, houve diferenças significativas entre os grupos meningioma e controle, nos aspectos físico (p = 0,002) e emocional (p = 0,004), e entre os grupos glioma de alto grau e controle, nos aspectos capacidade funcional (p = 0,003) e físico (p = 0,003). Conclusão: A cirurgia oncológica gerou alterações de humor e na qualidade de vida em ambos os grupos, independente do tipo histológico do tumor. Apesar da relevância do tema, ainda são poucos os estudos sobre o tema.

Objetivo O objetivo do presente estudo foi avaliar a associação do sono, depressão e ansiedade em pacientes com migrânea. Métodos Cinquenta pacientes do sexo feminino, provenientes de um centro terciário de tratamento de cefaleias, com o diagnóstico de migrânea segundo os critérios da International Headache Society, foram incluídas neste estudo. As pacientes foram avaliadas com os seguintes instrumentos: Migraine Disability Assessment test (MIDAS), Headache Impact Test (HIT), Hospital Anxiety (HADS-A) and Depression Scale (HAD-D), Índice de Qualidade do Sono de Pittsburgh (IQSP) e Escala de Sonolência de Epworth (ESE). Resultados As pacientes apresentaram alta prevalência de sintomas de ansiedade (60%) e de depressão (42%), má qualidade do sono (80%) e sonolência diurna (36%). Foi demonstrada correlação positiva entre a gravidade dos sintomas de ansiedade e HIT (p = 0,018; ρ = 0,334), ESE (p = 0,002; ρ = 0,426) e IQSP (p = 0,002; ρ = 0,426). Correlação positiva também foi demonstrada entre a gravidade dos sintomas depressivos e HIT (p < 0,001; ρ = 0,532), ESE (p = 0,035; ρ = 0,299) e IQSP (p = 0,016, ρ = 0,34). Não houve associação entre a qualidade do sono, a sonolência diurna e a gravidade da migrânea. A pontuação na HAD-D foi o principal preditor de impacto grave da migrânea. Conclusão Apesar da alta frequência de distúrbios do sono, o principal fator relacionado ao impacto da migrânea foi a gravidade dos sintomas depressivos.

The emerging field of lipidomics has identified lipids as key players in disease physiology. Their physicochemical diversity allows precise control of cell structure and signaling events through modulation of membrane prop- erties and trafficking of proteins. As such, lipids are important regulators of brain function and have been implicated in neurodegenerative and mood disorders. Importantly, environmental chronic stress has been associated with anxiety and depression and its exposure in rodents has been extensively used as a model to study these diseases. With the accessibility to modern mass- spectrometry lipidomic platforms, it is now possible to snapshot the extensively interconnected lipid network. Here, we review the fundamentals of lipid biology and outline a framework for the interpretation of lipidomic studies as a new approach to study brain pathophysiology. Thus, lipid profiling provides an exciting avenue for the identification of disease signatures with important implications for diagnosis and treatment of mood disorders.

Background: The Neonatal Behavioral Assessment Scale (NBAS, Brazelton & Nugent, 1995) is an instrument conceived to observe the neonatal neurobehavior. Data analysis is usually performed by organizing items into groups. The most widely used data reduction for the NBAS was developed by Lester, Als, and Brazelton (1982). Objective: Examine the psychometric properties of the NBAS items in a sample of 213 Portuguese infants. Method: The NBAS was performed in the first week of infant life (3 days±2) and in the seventh week of life (52 days±5). Results: Principal component analyses yielded a solution of four components explaining 55.13% of total variance. Construct validity was supported by better neurobehavioral performance of 7-week-old infants compared with 1-week-old infants. Conclusion: Changes in the NBAS structure for the Portuguese sample are suggested compared to Lester factors in order to reach better internal consistency of the scale.

O bebé humano, quando nasce, trás consigo uma diversidade de competências que lhe garantem uma pré adaptação e a sua sobrevivência no meio extrauterino. Este estudo tem como objectivo avaliar a preferência e a habituação do recém-nascido pela face/voz da mãe vs. uma pessoa estranha, bem como a identificação de variáveis que possam influenciar estas competências. A amostra, constituída por 50 bebés (com 1 a 5 dias de vida), foi avaliada através do paradigma da “preferência e habituação pela face/voz da mãe vs estranha” - uma situação experimental que envolve a participação da mãe e de duas figuras estranhas ao bebé, com o objectivo de avaliar o tempo que o bebé olha para cada pessoa, em três fases diferentes: 1) preferência, 2) habituação e 3) pós-habituação. Os resultados mostram a preferência pela face/voz da mãe, em detrimento da pessoa estranha. Porém, observa-se que, da fase de preferência para a fase de pós habituação, o tempo que o bebé olha para a mãe diminui e aumenta o tempo que olha para a figura estranha. Algumas características dos bebés (e.g., índice ponderal > 2.50) e das mães (e.g., coabitação, emprego) surgem relacionadas com resultados mais favoráveis (e.g., maior preferência pela face/voz da mãe na fase de preferência do que de pós-habituação e uma mais rápida resposta de habituação ao estímulo materno). Concluímos que, logo nos primeiros dias de vida, são observadas diferenças no comportamento dos recém-nascidos com a mãe e com uma estranha, o que pode condicionar o desenvolvimento do bebé e uma interacção adequada com a mãe.

BACKGROUND: Studies on the association between homocysteine levels and depression have shown conflicting results. To examine the association between serum total homocysteine (tHcy) levels and major depressive disorder (MDD) in a large community sample with an extended age range. METHODS: A total of 3392 men and women aged 35-66 years participating in the CoLaus study and its psychiatric arm (PsyCoLaus) were included in the analyses. High tHcy measured from fasting blood samples was defined as a concentration ≥15μmol/L. MDD was assessed using the semi-structured Diagnostic Interview for Genetics Studies. RESULTS: In multivariate analyses, elevated tHcy levels were associated with greater odds of meeting the diagnostic criteria for lifetime MDD among men (OR=1.71; 95% CI, 1.18-2.50). This was particularly the case for remitted MDD. Among women, there was no significant association between tHcy levels and MDD and the association tended to be in the opposite direction (OR=0.61; 95% CI, 0.34-1.08). CONCLUSIONS: In this large population-based study, elevated tHcy concentrations are associated with lifetime MDD and particularly with remitted MDD among men.
Psychodynamic interventions in cancer care I: psychometric results of a randomized controlled trial.

OBJECTIVE: This study aimed to assess the effectiveness of psychodynamic interventions in cancer care. METHODS: Between 2006 and 2009, each consecutive outpatient of the Oncology Center of the University Hospital of Lausanne was invited to participate in a trial evaluating the effects of psychological support. Accepting patients were randomly assigned to an immediate intervention or a delayed intervention [4-month waiting list]. Patients who declined support were asked to participate in an observational group [OG]. Socio-demographic and medical data, anxiety, and depression [HADS], psychological distress [SCL-90], alexithymia [TAS] and quality of life [EORTC] were recorded at baseline, and at 1, 4, 8, and 12-months follow-up. RESULTS: Of the 1973 approached patients, 1057 were excluded, 530 refused, and 386 were included with 196 of them participating in the OG. Of the patients in the intervention group [IG] [N = 190], 94 were randomized to the immediate intervention and 96 to the delayed intervention group (dIG). IG patients were younger, predominantly female, and had more psychological symptoms compared with those in the OG. Although patients of the IG and OG showed significant improvement in quality of life from baseline to 12-months follow-up, other outcomes [anxiety, depression, psychological distress, and alexithymia] remained unchanged. CONCLUSIONS: The intervention was not effective with regards to psychometric outcome. The results have to be interpreted in light of the study design [untargeted intervention], the low levels of psychiatric symptoms, dropout of symptomatic patients, and the high prevalence of alexithymia.

Showing smokers their own atherosclerotic plaques might increase motivation for smoking cessation, since they underestimate their own risk for smoking-related diseases. To assess the feasibility and optimal processes of studying the impact of carotid atherosclerotic plaque screening in smokers, we enrolled 30 daily cigarette smokers, aged 40-70 years, in an observational pre-post pilot study. All smokers underwent smoking cessation counseling, nicotine replacement therapy, a carotid ultrasound, an educational tutorial on atherosclerosis, baseline and 2-month motivation to change assessment, and assessment of smoking cessation at 2 months. Participants had a mean smoking duration of 34 years (SD = 7). Carotid plaques were present in 22 smokers (73%). Between baseline and 2 months after plaque screening, motivation for smoking cessation increased from 7.4 to 8.4 out of 10 (p = .02), particularly in those with plaques (7.2 to 8.7, p = .008). At 2 months, the smoking quit rate was 63%, with a quit rate of 73% in those with plaques vs. 38% in those without plaques (p = .10). Perceived stress, anxiety, and depression did not increase after screening. 96% of respondents answered correctly at least 80% of questions regarding atherosclerosis knowledge at baseline and after 2 months. In conclusion, studying the process of screening for carotid plaques for the purpose of increasing motivation for smoking cessation, in addition to counseling and drug therapy for smoking cessation in long-term smokers, appears feasible. The impact of carotid plaque screening on smoking cessation should be examined in larger randomized controlled trials with sufficient power to assess the impact on long-term smoking cessation rates.

Objective: To summarize the literature on alexithymia in cancer patients. Methods: The empirical literature published between 1972 and January 2010 was searched through MEDLINE, PSYINFO, EMBASE and the Cochrane Library. Key words were: alexithymia, affective symptoms, cancer, neoplasms. Results: The search identified 16 relevant studies which are methodologically problematic and show conflicting results. However, several interesting hypotheses emerge such as a possible link between alexithymia and the immune system, between alexithymia and quality of life, or between alexithymia, anxiety and depression. The question to what degree alexithymia in cancer patients is a trait or a state cannot be answered by these studies. Conclusions: A lack of methodologically sound studies and the large variations of results among studies suggest that the role of alexithymia in patients with cancer deserves more systematic research. Consequently, studies are needed which investigate the nature (state or trait) of alexithymia, its impact on cancer development and progression, as well as its influence on compliance and on the underestimation of psychological distress and psychiatric outcome in cancer patients.

BACKGROUND: Classically, clinical trials are based on the placebo-control design. Our aim was to analyze the placebo effect in Huntington's disease. METHODS: Placebo data were obtained from an international, longitudinal, placebo-controlled trial for Huntington's disease (European Huntington's Disease Initiative Study Group). One-hundred and eighty patients were evaluated using the Unified Huntington Disease Rating Scale over 36 months. A placebo effect was defined as an improvement of at least 50% over baseline scores in the Unified Huntington Disease Rating Scale, and clinically relevant when at least 10% of the population met it. RESULTS: Only behavior showed a significant placebo effect, and the proportion of the patients with placebo effect ranged from 16% (first visit) to 41% (last visit). Nondepressed patients with better functional status were most likely to be placebo-responders over time. CONCLUSIONS: In Huntington's disease, behavior seems to be more vulnerable to placebo than overall motor function, cognition, and function
